Katherine Breann Cooper, 22, was killed on May 23, 2014, in Isla Vista, California, during a series of attacks near the University of California, Santa Barbara campus. A student pursuing a double major in art history and classics with an interest in archaeology, Cooper was an active member of the Tri Delta Sorority and was described as vibrant and compassionate by family and friends.

The attacker, identified as Elliot Rodger, had stabbed three men in his apartment before opening fire in Isla Vista. Cooper and her friend Veronika Weiss were shot outside the Alpha Phi sorority house. The rampage lasted about ten minutes and left six people dead and fourteen injured.

Investigators noted Rodger had posted videos and a manifesto online and had a history of mental health problems. Families later pursued litigation alleging failures by the Sheriff’s Office and the apartment complex to act on warning signs. Memorials and changes to campus safety followed Cooper’s death.

If anyone knew Katie, her routines, or has information about that day, please share what you remember.
